In this review, we will be comparing Diamond 220 and TSi200, two Passive Bookshelf speakers from Wharfedale and Polk Audio. Let's have a brief look at the main features
of Wharfedale 220 and Polk TSi200 first before getting into our more
detailed comparison.
What size room are the Wharfedale 220 and Polk TSi200 speakers good for?
The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:
In the following sections, we will get into more detail in order to better understand how the Wharfedale 220 and Polk TSi200 compare and hopefully end up with enough arguments to decide which one of these loudspeakers is the better choice for you.

Diamond 220 features a 1" Dome Tweeter and 1 x 5" Woven Kevlar Woofer with a Crossover frequency at 2200Hz. On the other hand, the TSi200 features a 1" Dome Tweeter and 2 x 5.25" Organic Fiber Woofer with a Crossover frequency at 2500Hz.
Frequency Response
Diamond 220 has a frequency range of 56-20k Hz whereas TSi200 has a frequency range of 50-24k Hz. With a minimum frequency of 50Hz, the TSi200 can go significantly deeper on the low side and provide stronger bass compared to the Diamond 220's min frequency of 56Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Bookshelf class in our database.

None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Diamond 220 and TSi200 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. Diamond 220 sensitivity is rated at 86 dB and the TSi200's is at 89 dB. This 3 dB difference makes the Polk TSi200 a more sensitive speaker compared to Wharfedale 220, hence will play louder with the same amount of watts.
Sensitivity

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Diamond 220 can handle a max power of 150 watts RMS from the amp the whereas Diamond 220 has a max power handling value of 100 watts RMS , 50 watts less than the TSi200.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Diamond 220 features Post posts which make bi-amping or bi-wiring possible. TSi200 has a Pair of 5-way binding posts - Gold-plated which doesn't feature bi-amping/bi-wiring.
Wharfedale 220's Post terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Diamond 220 has a bottom firing port whereas TSi200 has a rear firing ports. Wharfedale 220's bottom-firing port gives more flexibility in placement in regards to proximity to walls compared to Polk TSi200 with its rear-firing port.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Wharfedale 220's and Polk TSi200's external dimensions. Wharfedale 220 has external dimensions of 315.0 x 174.0 x 255.0mm ( 12.4 x 6.8 x 10.0inch) whereas Polk TSi200 has external dimensions of 392.1 x 203.2 x 298.5mm ( 15.4 x 8.0 x 11.7inch) .
Polk TSi200 is clearly the larger of the two speakers. Its body is 29.2mm wider, 77.1mm taller and 43.5mm deeper than Wharfedale 220.
Below you can see the front view size comparison of Wharfedale 220 and Polk TSi200 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Wharfedale 220 is approximately 443.7cm2 / 68.8inch2 and base area of the Polk TSi200 is approximately 606.6cm2 / 94.0inch2. The Diamond 220 requires 27% less surface area than the TSi200 which gives it a small advantage on placement in tight spaces.
Here is an another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Wharfedale 220 weighs 5.32kg / 11.7lbs and the Polk TSi200 weighs 7.71kg / 17lbs. This makes the TSi200 45% heavier than the Diamond 220.
Here is a comparison of how Diamond 220 and TSi200's weights compare with the average, max and min weights in Passive Bookshelf class.
